Dodge, 515 Washington St. W., Charleston, W. Va. 25302 Filed Oct. 8, 1965, Ser. No. 494,170 1 Claim. (CI. 51-26) ABSTRACT OF THE DISCLOSURE A brake contour spinning mechanism which is leveled up with the brake drum by a pair of adjustable arms and otherwise suspended by a belt from the brake drum for allowing the weight of the machine to maintain the belt in taut relation as the motor spins the brake drum.

The present invention relates to a brake contour spinning mechanism, and more particularly relates to a machine which is designed to be leveled up with the brake drum by a pair of adjustable arms and otherwise suspended by a belt from the brake drum that allows the weight of the machine to maintain the belt in a taut relation as the motor spins the brake drum.

It is also within the contemplation of the present invention to provide a reversible motor for allowing improved equalizing of the contour of each brake shoe on the brake drum by using the reversible motor which is mounted from the brake drum and by the pair of adjustable arms.

An object therefore of the invention is to develop and provide a machine which is to principally spin the brake drum With an abrasive within the drum, so that the shoes are adjusted out against the abrasive, and as the drum spins, the lining is contoured so as to make all of the surface of the shoes come in contact with the drum and at the same time it centers the shoes, respectively, within the drum.

The above and other objects and advantages of the invention will become apparent upon full consideration of the following detailed description and accompanying drawings in which:

FIG. 1 is a perspective view showing the features of the brake contour spinner as it drives a brake drum for an automobile, the automobile being shown in broken away v1ew;

FIG. 2 shows a front elevation view thereof;

FIG. 3 shows a plan elevation view thereof; and

FIG. 4 shows a side elevation view thereof in accordance with the preferred embodiment of the invention.

Referring now to the drawings, there is shown a brake contour spinner mechanism in which there is a machine or motor mounting frame 12, a sole pair of mounting arms, 14, 14 for supporting the frame from the ground 16, and in which the pair of mounting arms is shown to be capable of being adjusted in length so that the height of the mounting frame 12 may be adjusted accordingly, as desired.

Centrally disposed upon the mounting frame 12, there is an electric motor secured by bolts '22, 22 to the frame, and which has at a distal end from the mounting arms 14, 14, a rotatably mounted pulley 24 which is secured to the axis 26 of the motor 20. The pulley 24 is disposed in planar alignment with a suspended brake drum 30, and the suspended brake drum 30 of the automobile 32 is driven by a belt 34 so that the frame 12 is suspended by the pulley 24 as well as the belt 34 driving the brake drum 30 by rotation of the motor 20.

In this way, the objects and advantages of the invenice tion are realized and in order to secure stability of the mounting frame while in use, a metal or other heavy weight 38 may be provided, as shown, to assure that the incumbent vibrations of the motor 20 as it rotates does not walk the mounting frame on the supporting mounting arms about and away from the automobile 32, so that the belt 34 is maintained in alignment between the pulley 24 and the brake drum 30. In this way, as the drum spins about its axis by virtue of the motor 20 which may be either a uni-directional or reversible motor, the motor causes the brake drums and the shoes thereon including the lining so that the lining is contoured to make all of the shoes surface come in contact with the drum and at the same time it centers the shoe within the drum.

The adjustable mounting arms 14, 14 are capable of being adjusted by means of the bolt and slot action provided by bolts 50, 50 and the slot 52, 52. The mounting arms are hingedly connected to the mounting frame by hinge elements 54, 54. The motor mounting frame may have disposed thereon a reversing switch 56 for controlling the reversible motor 20, as is well known. The necessary electrical connections may be provided from a plug and socket arrangement or may be provided by means 60, which terminates in a plug receptacle 62. On the underside of the mounting frame on the end opposite the adjustable arms 14, 14, there are provided a pair of swivel casters 66, 66 so that after the belt 34 has been disengaged from the brake drum 30 and while the free end of mounting frame 12 is supported from the ground 16 by caster 66, the handle 68 may be used to remove the brake contour spinner mechanism 10 away from the automobile 32.

Additional embodiments of the invention in this specification will occur to others and therefore it is intended that the scope of the invention be limited only by the appended claim and not by the embodiment described hereinabove. Accordingly, reference should be made to the following claim in determining the full scope of the invention.

What is claimed is:

1. A brake contour spinner comprising a motor mounting frame, a reversible motor mounted on one end of said frame, a pulley driven by said motor, a sole pair of adjustable mounting arms for supporting the frame from the ground located on the other end of said frame, a belt mounted from said pulley for support of the frame from the ground at said one end of said frame when the belt passes over a suspended brake drum having .a shoe with brake lining therein, the drum being spun by the motor so that the brake lining is contoured to make all the shoes surface come in contact with the drum and, at the same time, it centers the shoe in the drum, a dead weight supported on said frame in between the pair of adjustable mounting arms, a pair of swivel casters disposed on the said one end of the mounting frame, and a handle mounted from the mounting frame between the adjustable mounting arms, the adjustable mounting arms being adjustable by means of a bolt and slot structure.
